10.1. CouplingIn models Mondeo with a mechanical transmission at each change of transfer the engine by means of one-disk dry coupling separates from a transmission – for tens years repeatedly approved decision. For those who works independently, one-disk dry coupling possesses, certainly, that lack that the worn out details, such as a conducted disk or the bearing of deenergizing of coupling, in case of repair are not «on a kind». In Mondeo for this purpose it is necessary to separate a transmission from the engine and to dismantle: work which demands serious knowledge and special tools. Our council: transfer better work on replacement of coupling of a special workshop.

Coupling consists of a flywheel 1, a coupling disk (a conducted disk) 2 and a press disk of coupling (an automatic drive of coupling) 3. In all Mondeo with a mechanical transmission press the coupling disk has мембранную a spring. |
Coupling in details
Engine flywheel: rotates together with cranked shaft and it is strongly connected to it.
Coupling disk (conducted disk): settles down on an entrance shaft of a transmission and rotates together with it, can is longitudinal to move. On both parties «steel disk» приклепаны frictional linings. External diameter of a disk of coupling in Mondeo, depending on the used engine, is distinguished: 1,8 l/2,0 of l Duratec-HE = 228 mm; 2,5 l Duratec-VE/DuraTorg-DI = 240 mm.
Press a coupling disk (a hydraulic drive of coupling): it is screwed strongly together with an engine flywheel. Presses a floating disk of coupling with the help тарельчатой springs to a flywheel.
The bearing of deenergizing of coupling: (in all models Mondeo it is built in directly the executive cylinder of coupling). Settles down аксиально and moves on a deenergizing shaft. Transfers created by a coupling pedal clamping effort on тарельчатую a spring of a press disk of coupling. Press the coupling disk thanks to it is released – the conducted disk loses clamping effort to an engine flywheel.
The adjusting automatic machine: in all models Mondeo гидравлически working coupling automatically regulates the ordered backlash of a pedal of coupling. Therefore in burdensome adjusting works there is no necessity. As soon as coupling in yours Mondeo slips, recognise that replacement or, probably is necessary, the primary valve of pressure is clamped "only".

How coupling functions?
Coupling backlash: at not loaded pedal of coupling the distance from a press disk of coupling is maintained by the bearing of deenergizing of coupling. To similarly deterioration of a disk of coupling the coupling backlash, with run increase, becomes always less: тарельчатая the spring of a press disk approaches with the bearing of deenergizing of coupling. As soon as the bearing «without a backlash» will adjoin to тарельчатой to a spring, press the disk is released. The clamping effort of a conducted disk to adjoining surfaces of a flywheel and a press disk thereof automatically goes down. If the backlash cannot be corrected more, coupling cannot transfer a twisting moment of the engine without проскальзывания in a transmission any more – the engine flywheel does not concern a conducted disk.
Separation: If to press a coupling pedal thereby by means of the bearing of deenergizing of coupling elasticity of a press disk is weakened. It is released and – at full отжатии couplings – leaves: the conducted disk freely rotates between a press disk and a flywheel.
Coupling inclusion: at coupling inclusion in management of coupling «return movement» separation process practically proceeds. Released тарельчатая the spring of a press disk gradually presses a conducted disk to a flywheel. At this stage frictional linings quickly slide on a flywheel and a press disk of coupling. At a disconnected pedal of coupling the clamping effort of a hydraulic drive as a result is so great, paternal the flywheel even stops also connection between a flywheel and a press disk becomes a reality. Now capacity of the engine is completely transferred in a transmission. |

"Murderer" of coupling The doubtful glory of "murderer" of coupling hastens forward any motorist who absolutely easy infuriates the vehicle «the howling engine» and sliping coupling: murderers of coupling regularly dramatize the "heavy" pressing a coupling pedal "hot" dramas between frictional linings of a disk of coupling, a press disk and a flywheel as round revolving coupling there are temperatures, which quickly приканчивают a disk of coupling and press a disk.
The driver who during movement constantly "parks" the foot on a coupling pedal, thereby pays the comfort equally raised deterioration.
Other bad habit of "murderer" of coupling: instead of passing to idling and to put a manual brake (a lay brake), it holds the car on biases or before red light of a traffic light on the established first transfer, coupling and gas pedals thus are «on weight». For it it "will thank" not only coupling, but also in due course also the bearing of deenergizing of coupling, and also the adjusting bearing of a cranked shaft.
If you do not sympathise with "murderer" of coupling before a red traffic light switch off coupling is better and establish the first transfer only when the traffic light is switched to yellow light. And during movement put the sole – between gear changes – nearby, instead of on a coupling pedal. |
